Korean sunscreen comes in more textures than most people expect: creams, serums, essences, sticks and tone up formulas, all sitting under the same SPF50+ PA++++ label. The one you pick changes how likely you are to actually wear it every morning, and in a country with South Africa's UV levels, wearing it is the part that decides everything else.
Short version: a sun cream is the most reliable morning base layer. A sun serum or essence is thinner and sits better under makeup. A sun stick is a reapplication tool, not a replacement for your morning layer. A tone up formula adds a light finish on top of the protection. Here is how to tell them apart and use each one properly.

What SPF and PA actually measure
SPF is the UVB number
SPF measures how much UV radiation it takes to redden your skin with the sunscreen on, compared with the amount that reddens bare skin, according to the Skin Cancer Foundation. UVB is the wavelength band mainly responsible for sunburn. The American Academy of Dermatology puts the practical threshold at SPF 30 or higher, noting that SPF 30 blocks 97 percent of UVB rays. Most Korean face sunscreens are labelled SPF 50+, which sits comfortably above that line.
PA is the UVA number
PA is the second rating printed on Korean and Japanese sunscreens, written as PA+ through to PA++++. It exists because the SPF figure on its own tells you almost nothing about UVA. UVA rays go deeper into the skin than UVB and, per the Skin Cancer Foundation, are the chief cause of wrinkles, sagging and other signs of ageing, while UVB damages the upper surface and drives sunburn.
That gap between the two ratings is not theoretical. A 2026 study measuring UVA protection factor under ISO 24442 across 38 different SPF 50 and SPF 50+ sunscreens found UVA protection factors ranging from 3.6 to 46.6, with about one third of products failing EU recommendations, and no reliable relationship between SPF and UVA protection factor values. Two sunscreens with identical SPF numbers can protect very differently against UVA, which is why checking for a PA rating (or a broad spectrum claim) alongside the SPF number is worth doing.
Why this matters more here than in most places
The Cancer Association of South Africa states plainly that South Africa has one of the highest monitored UV levels in the world, resulting in one of the highest skin cancer rates globally. Their guidance: an SPF between 20 and 50 (30 to 50 for fair to very fair skin), applied 20 minutes before going outside and reapplied at least every two hours, after towel drying, perspiring or swimming. They also advise staying out of direct sun between 10am and 4pm where possible.
The World Health Organization sets the trigger point at a UV index of 3. From 3 to 7 the advice is to seek shade during midday hours and use a shirt, sunscreen and hat, and at 8 and above to avoid being outside during midday hours entirely. Across most of South Africa, most of the year, the index clears 3 without much effort. That is why sunscreen here is a daily routine step rather than a beach product, and it is one of the reasons the buying decision is worth thinking through properly. Our guide to buying Korean skincare in South Africa covers the wider checks worth running before you order anything new.
The four formats, and what each one is for
| Format | Feel | Best for | Role |
|---|---|---|---|
| Sun cream | Rich, even spread | Normal, dry, combination skin | Morning base layer |
| Sun serum / essence | Thin, fast absorbing | Oily, congestion-prone, under makeup | Morning base layer |
| Sun stick | Solid balm | Anyone reapplying over makeup | Midday top-up |
| Tone up / tinted | Cream with a light finish | Anyone who wants to skip the white cast | Morning base layer |
Sun creams
The standard format, and the one to default to for your morning layer. Sun creams hold enough emollience to spread evenly across a full face without dragging, which matters because even coverage is what actually delivers the number on the bottle. Best suited to normal, dry and combination skin, and to anyone who wants one product to do the whole job in the morning.
A hybrid, skin-soothing sun cream that spreads evenly without pilling under makeup.
Also worth a look in this category: the Mary&May CICA Soothing Sun Cream SPF50+ PA++++, a gentler vegan option built for sensitive and barrier-compromised skin.
Sun serums and sun essences
Thinner, faster to absorb, and closer to a hydrating serum in feel than to a traditional sunscreen. This is the category that has grown fastest in K-beauty, and it exists mainly to solve two complaints: heaviness and pilling under makeup.
A high-performance daily essence built for sensitive, irritated or heat-flushed skin.
The Tocobo Cica Calming Sun Serum SPF50+ PA++++ and the Arencia Deep Water Surge Sun Serum sit in the same group. Worth knowing: a lighter texture makes it easier to under-apply, because a thin fluid feels finished on the skin before you have used enough of it. Measure rather than eyeball.
Sun sticks
A solid balm in a twist-up tube. Sticks are the practical answer to the reapplication problem, because you can swipe one over a made-up face in a car park without needing a mirror, a basin or clean hands.
Lightweight, portable, strong UVA/UVB protection in a stick you can carry anywhere.
The Tocobo Vita Waterproof Sun Stick SPF50+ PA++++ and the Tocobo Cica Cooling Sun Stick are built for the same job. What a stick is not is a shortcut for your first application of the day: getting a full measured layer out of a stick takes many more passes than most people make, so treat it as your top-up and let a cream, serum or essence do the base layer.
Tone up and tinted formulas
These add a light finish or colour to the sunscreen itself, which is how many of them sidestep the white cast complaint that keeps people from wearing SPF daily.
Brightening tone-up sunscreen with PDRN and niacinamide for an even, radiant finish.
Treat the finish as cosmetic and judge a tone up product on its SPF and PA rating the same way you would any other sunscreen.
The amount almost everyone gets wrong
The AAD recommendation is at least a teaspoon for the face, and about an ounce (roughly a shot glass) for the whole body, applied to dry skin 15 minutes before going outdoors. CANSA says 20 minutes before. Either way, the point is that the sunscreen goes on before you leave, not once you are already standing in the sun.
A teaspoon is considerably more product than most people use. If your bottle is lasting six months, the number on the label is not the number your skin is receiving. This is the single change that makes the biggest difference to how a sunscreen performs, and it costs nothing to fix.
Reapplying through an ordinary day
Two hours is the interval both the AAD and CANSA give, with an extra reapplication after swimming, sweating or towel drying. That is straightforward on a Saturday and awkward on a Tuesday, which is exactly why the stick format exists. A workable pattern for a normal working day:
- Morning: a full measured layer of sun cream, serum or essence as the last step of your skincare, before makeup.
- Midday (if you have been outside or near a window for long stretches): a stick over the top, several passes per area.
- Mid afternoon or before any outdoor stretch: reapply again.
- After swimming, sport or a sweaty commute: reapply regardless of the clock.
If your day is entirely indoors and away from windows, the reapplication load drops. Match the effort to the exposure rather than to a rule.
Matching a format to your skin
If your skin runs oily or is prone to congestion, a sun serum or essence usually sits better than a rich cream, and the rest of your routine matters as much as the SPF itself. Our post on a Korean skincare routine for oily skin in South Africa sets out the steps around it.
If your skin is reactive or flushes easily, look for simpler, fragrance-light formulas and patch test on the jaw for a few days before committing to full face use. Our redness and sensitivity range is filtered for that kind of skin.
If uneven tone is what you are working on, daily UV protection is the step everything else in your routine sits on top of, given how directly UVA exposure is tied to visible ageing. The uneven tone collection is where the rest of that routine lives.
Taking it off at night
Water resistant and long-wear sunscreens are designed to stay put, which means a splash of water and a gel cleanser will not always shift them fully. An oil cleanser as the first step of a double cleanse handles SPF, then follow with your usual water-based cleanser. If you have moved to a heavier or more water-resistant sunscreen for summer, this is the step to add at the same time.
Where to start
If you are choosing your first Korean SPF, start with a sun cream, serum or essence as your daily base layer, and add a stick later once you know how often you actually need to top up. Sunscreen is not a product that rewards buying the most expensive option. It rewards buying one you will use a full teaspoon of, every morning, without thinking about it.

Frequently asked questions
What SPF should I use in South Africa?
CANSA recommends SPF 20 to 50 for daily wear, and SPF 30 to 50 for fair to very fair skin. Most Korean sunscreens sit at SPF 50+, which comfortably covers that range.
What does PA++++ mean?
PA is the UVA rating printed on Korean and Japanese sunscreens, scaled from PA+ to PA++++. It is separate from SPF, which only measures UVB protection, so a high SPF with no PA rating does not tell you how well a sunscreen protects against UVA-driven ageing.
How much sunscreen should I actually be applying?
At least a teaspoon for the face, per the American Academy of Dermatology, applied 15 to 20 minutes before you go outside. Most people use far less than this without realising it.
Is a sun stick enough on its own?
No. A stick is built for reapplication over an existing layer, not for your first application of the day. It takes many more passes than most people give it to deliver a full measured dose.
What is the difference between a sun cream and a sun serum?
A sun cream is richer and spreads evenly across the full face, making it the more forgiving daily base layer. A sun serum or essence is thinner, absorbs faster, and sits better under makeup, but is easier to under-apply because it feels finished on the skin sooner.
Do I still need sunscreen on a cloudy day?
Yes. The WHO's UV index guidance is about cumulative exposure, not visible sunshine, and South Africa's UV levels clear the WHO's protection threshold on most days of the year regardless of cloud cover.
